Net Structure for Ball Game Court

ABSTRACT

A net structure for ball game court includes a plurality of wefts, warps, meshes formed at the nodes where the wefts and the warps intersect, and a plurality of grids are defined by the wefts and warps, and the wefts and the warps are made of a rope element woven one another. Several enhanced areas are formed in predetermined parts of the net structure employing double wefts and warps.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a net structure for ball game court, and more particularly, to a specially constructed net structure for tennis court, wherein the net structure is dexterously strengthened.

2. Description of the Prior Art

The people in the world get more concerned and interested with the ball games of various kinds as they are boomed up by the international television broadcast. Take tennis game for example, it really has been one of the most popular ball games.

Speaking of the tennis games, there needs good playing equipment such as the racket and ball, and a qualified tennis court which being in compliant with the related standards scored by the service side lines, the boundary lines, and the service lines to define the special regions. Above all the center net is the most important. As shown in FIG. 1 and FIG. 2, a net structure 1 is secured to the poles 2 erected at two sides for support so as to divide the whole court into two sections. The traditional net structure 1 is usually made of polymer material employing single string of rope as wefts 1 a and warps 1 b mutually intersected one another to form a plurality of grids IC and meshes 1 d, the meshes 1 d are the intersection nodes of the wefts 1 a and the warps 1 b.

As it is mentioned, the conventional weft 1 a and warp 1 b are formed of a single string of rope. It is apt to break or become loose when being pulled at two sides on the poles 2 because of its degenerate structural strength especially in outdoor use. Moreover, exposure to the sunlight, wind and rainfall for a long time further accelerates its deterioration. Besides, forming a mesh 1 d by tying is not reliable as it is hard to keep the size of the grids IC unchanged when the non-uniform tensile force is applied on the net structure 1.

SUMMARY OF THE INVENTION

The present invention is to provide a net structure for ball game court essentially comprising a plurality of wefts, warps, meshes and grids, wherein the wefts and warps are woven one another to form meshes. In the predetermined areas, the double layered wefts and warps are employed so as to form enhanced areas in the net structure.

The net structure for ball game court constructed as such is reliably strengthened and tightened, and the provision of specially enhanced areas further upgrades the quality and prolongs the lifespan of the entire net structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 3 and FIG. 4, the schematic views of the net structure for ball game court, the net structure 10 is constructed substantially similar to that of a conventional one. Each side of the net structure 10 is secured to a side support pole, and the net structure 10 includes a plurality of wefts 11 and warps 12 each of them intersected to form a mesh 13, and a plurality of grids 14 are formed by the wefts 11 and the warps 12 encircling thereof so as to define a visible barrier between the two half courts thereby interrupting the ball which touches it.

As shown in FIG. 5 and FIG. 6, the kernel of the present invention lies in that a rope element 101 is constructed by the plurality of polymer (plastic) made wefts 11 and warps 12 woven together instead of using a single string of rope. By so the net structure 10 as a whole is effectively strengthened and the meshes 13 are uneasy to deform or loosen.

It should be pointed out that the net structure 10 of the present invention has no particular manner to form, or to follow particular procedures as well. It can be formed using a single rope element 101, or several ones to weave to form the wefts 11, warps 12 and meshes 13 therebetween. Alternatively, a basic unit woven net section can be constructed first using several rope elements 101, and then jointing the basic units of woven net sections in order to form the whole net structure 10. In other words, the fractionary sections of the net structure 10 including the wefts 11, warps 12 and meshes 13 are jointed together one by one to make up a whole net structure 10. It is considered a preferable construction technique for the present invention, but by no means, limited as the only choice.

Referring to FIG. 5 and FIG. 6, an enhanced area 15 is formed in the upper half or lower half area of the net structure 10. The enhanced area 15 is formed by intercalating a machine thread 102 between the front and rear wefts 11 to reinforce the strength of the enhanced are 15. Meanwhile, the machine thread 102 may be woven with the wefts 11 so as to further ensure the strength of the enhanced area 15.

Applicant further provides attachments 1-5 of practical pictures to show the net structure of the present invention.

In all, the net structure of the present invention has several advantages compared with the conventional one, namely:

1. The net structure 10 is woven from a plurality of rope elements 101 to form the wefts 11, warps 12 and meshes 13 so as to ensure better strength than that made of a traditional single string of rope.

2. The meshes 13 are strong enough to withstand the external destructive force so as to prevent deformation of the grids 14.

3. The enhanced area 15 formed of intercalation of the reinforced machine threads increases its resistance to the wind force and external attack.

4. The compact and tight woven structure contributes to improving the durability of the net structure 10.
